R100R Front Brake Pad Rub-how much is normal, if any?

Been reading thru the brembro rebulid threads and the like.

I have a 95 mystic

Before diving in on the rebuild, just wondering how much pad rub, if any is normal on the brembro set up. Should there be none at all or is a little rub okay? I have a little rub. Wheel turns fine but I can hear the pads rubbing pretty clearly.

I understand about the brake line not allowing back-flow properly, piston o rings getting dirty etc just not sure if I need to do the rebuild.

I did see on the MG cycle site a rebuild kit for brembro

just hearing that hissing sound when I spin the front wheel. Should it be totally quiet?

What is the disassembly procedure on the calipers?

You may get some noise, but as long as the brake isnt dragging, shouldnt be a problem.
When I got my GSPD, the front caliper was semi seized, and would heat up, and drag real bad on a short run.
I pulled the caliper apart, and cleaned the pistons, made sure they moved freely, and no more issues after that. Until I fitted the 6pot caliper

Un-Hacked?

Hey Johno,

What do you call "un-hacked"? I have a 90 GSPD that I try not to make any mods to. I call it "stock". I'm an old guy (53). Is it the same thing?

Sorry, didnt mean to Hi-jack the thread.

I remember the first time I did my front brake on the GSPD. Made the classic mistakes (gee, I guess I should have put some shims in there b4 I drained the fluid) but when I got it right it did not drag.

PS: If you're ever in the "States" look us up! If you're riding a GSPD we're good for a stop-over. Not too far from NYC. Everybody seems to love NYC (we go there a lot our selves).

Glad you two had a chance to catch up and chat....

What is the disassembly procedure on the calipers for cleaning and rebuild.

Thanks...

If your brakes are not dragging, and getting hot, work OK, I wouldnt worry about it.

Thanks for the comment. I agree, discs are cool to the touch after a ride so I'm gonna leave it be for now. After flushing the brake system, the braking improved and the pads tightened up a bit around the discs with new fluid in the system.
